Guinea Pigs burrowing under eachother

[Piggie Life]

When I have Fudge & Aero out on my lap for lap time they do the usual things, make noise eat food from my hand etc. But Aero has started doing something really weird; she tries to burrow underneath Fudge and it's as if she is trying to hide. She just sticks her head underneath Fudge and stay there. She doesn't seem unhappy though as she purrs a lot and eats happily from my hand. What could this be?

My Ruby hides under any of the other girls, but little Tia will use the older girls as a lookout perch and stand with her front feet on the older girls backs
